Boundary actions of CAT(0) spaces: topological freeness and applications to -algebras
Xin Ma, Daxun Wang, Wenyuan Yang
In this paper, we study topological dynamics on the visual boundary and several combinatorial boundaries associated to spaces. Through verifying the freenes…

Ancona inequalities along generic geodesic rays
Kairui Liu, Wenyuan Yang
This paper presents several versions of the Ancona inequality for finitely supported, irreducible random walks on non-amenable groups. We first study a class of Morse subsets with…

Hausdorff Dimension of non-conical and Myrberg limit sets
Mahan Mj, Wenyuan Yang
In this paper, we develop techniques to study the Hausdorff dimensions of non-conical and Myrberg limit sets for groups acting on negatively curved spaces. We establish maximality…
